Please refer to XF86Config(5x)
for general configuration
details and for options that can be used with all input drivers. This section
only covers configuration details specific to this driver. For better understanding
please read also the CTS and various IRT manuals which are available in
"pdf" format from Citron web page www.citron.de or directly from Citron.

This value is responsible
for the button number that is returned within the xf86PostButton event
message

Range: "0" - "255"

Default: "1"

Option ButtonThresholdvalue

This value is responsible for the button threshold. It changes the pressure
sensitivity of the touch. A higher number corresponds to a higher pressure.

Note: This feature is only available with pressure sensitive hardware.

Range:
"0" - "255"

Default: "20"

Sleep-Mode

If the IRT is in Doze-Mode and Touch
Zone is not interrupted for another certain span of time, the so-called
Sleep-Mode is activated. The Sleep-Mode decreases the scan rate of the beams
even further than the Doze-Mode does (see below). This way the life expectancy
of the beams is prolonged and the power consumption of the IRT is reduced.
As soon as an interruption of the Touch Zone is detected, the Sleep-Mode
is deactivated and the Touch Zone will again be scanned with the maximum
speed. With the Sleep-Mode activated, depending on the set scan rate the
IRT's response time can be considerably longer as in normal operation. If,
for example, a scan rate of 500 ms / scan is set, it may last up to a
half of a second until the IRT detects the interruption and deactivates
the Sleep-Mode.

Option SleepModemode

This value is responsible for the
sleep-mode of the touch.

Determines the behaviour of the Sleep-Mode.

0x00
No message at either activation or deactivation

0x01 Message at activation

0x02 Message at deactivation

0x03 Message at activation and deactivation

0x10 GP_OUT output set according to the Sleep-Mode status

Values: "0"
"1" "2" "3" "16"

Default: "0"

Option SleepTimetime

This value is responsible
for the sleep-time of the touch. It is the activation time in seconds ("0"
= immediately activated, "65535" = always deactivated).

Range: "0" - "65535"
[s]

Default: "65535" => deactivated

Option SleepScanscan

This value is
responsible for the scan-time of the touch. This is the time interval between
two scan operations while in Sleep-Mode. The time interval is set in steps
of milliseconds.

Range: "0" - "65535" [ms]

Default: "500"

Option PWMAdjSrcvalue

Option PWMAdjDstvalue

These parameters are used to adjust the brightness
of different backlight inverters. At the moment 2 backlight inverters are
used: 0=TDK 1=AC. If you want a AC backlight inverter to behave like
an AC type you have to set PWMAdjSrc to 0 (TDK) and PWMAdjDst to 1 (AC).

Range: "0" - "1"

Default: "-1" (no adjustment)

Option PWMActivevalue

This value determines the mark-to-space ratio of the PWM output while in
normal operation (sleep-mode not active). Higher values result in longer
pulse widths. This output signal can be used in conjunction with the Citron
AWBI to do backlight-dimming via the touch.

With
this mode every interruption of the infrared beams will activate a ButtonPress
event and after the interruption a ButtonRelease event will be sent.

"2""
= ClickMode Dual

With this mode every interruption will sent a Proximity
event and every second interruption a ButtonPress event. With the release
of the interruption (while one interruption is still active) a ButtonRelease
event will be sent.

"3"" = ClickMode Dual Exit

With this mode every interruption
will sent a ProximityIn event and every second interruption a ButtonPress
event. With the release of the interruption (while one interruption is still
active) no ButtonRelease event will be sent. Only if all interruptions are
released a ButtonRelease followed by a ProximityOut event will be sent.

"4"" = ClickMode ZPress

With this mode every interruption will sent a
ProximityIn event. Only if a certain pressure is exceeded a ButtonPress
event will occur. If the pressure falls below a certain limit a ButtonRelease
event will be sent. After also the interruption is released a ProximityOut
event is generated.

"5"" = ClickMode ZPress Exit

This mode is similat
to "Clickmode Dual Exit". The first interruption of the beams will sent
a ProximityIn event. Only if a certain pressure is exceeded a ButtonPress
event will occur. If the pressure falls below a certain limit no ButtonRelease
event will be sent. After the interruption is also released a ButtonRelease
followed by a ProximityOut event is generated.

Range: "1" - "5"

Default:
"1" (ClickMode Enter)

Option Originvalue

This value sets the coordinates
origin to one of the four corners of the screen. The following values are
accepted: "0" TOPLEFT: Origin set to the left-hand side top corner. "1" TOPRIGHT:
Origin set to the right-hand side top corner. "2" BOTTOMRIGHT: Origin set
to the right-hand side bottom corner. "3" BOTTOMLEFT: Origin set to the left-hand
side bottom corner.

Range: "0" - "3"

Default: "0" (TOPLEFT)

Doze-Mode

If
for a certain span of time the Touch Zone is not interrupted, the so-called
Doze-Mode is automatically activated. The activated Doze-Mode slightly decreases
the scan rate of the beams. This way the power consumption of the IRT is
reduced. As soon as an interruption of the Touch Zone is detected, the
Doze-Mode is deactivated and the Touch Zone will again be scanned with
the maximum speed.

Option DozeModemode

This value is responsible for the
doze-mode of the touch.

Determines the behaviour of the Doze-Mode.

0x00 No

message at either activation or deactivation

0x01 Message at activation

0x02 Message at deactivation

output is already controlled by the Sleep-Mode it is no longer available
as an output port anymore.

Values: "0" "1" "2" "3" "16"

Default: "0"

Option DozeTimetime

This value is responsible for the doze-time of the
touch. It is the activation time in seconds ("0" = immediately activated,

Default: "65535"
=> deactivated

Option DozeScanscan
